^0 tlie Client^ of 



Gentlemen: A few words regarding the recent change 
in the name of our firm. 

Our Patent business since its inception has been undei 
the personal supervision of our Col. J. C. Smith, who wil? 
continue to supervise the same. 

The retirement of Messrs. Chipman and Hosmer, (wliich 
was amicably effected,) will not therefore create any change 
in the management of our Patent business. 

The business is continued at the same office, upon the 
same terms, and substantially by the same experts and 
operative force as before the name of the firm was 
changed. 

Hereafter, please address

INTRODUCTION. 



This pamphlet is published for the purpose of pointing 
out to those interested in such matters the law and busi- 
ness details applying in this country to the procurement 
of Letters Patent^ and of giving general information as 
to the method of obtaining Patents in Europe. All facts 
or information coming within the wants of inventors, and 
those desiring the service of Patent Attorneys or Solicitors, 
will be promptly furnished upon request. Our experience, 
favorable location within a short distance of the Patent 
Department, where all the records^ models, and accu- 
mulating archives are accessible; our successful and in- 
creasing business; our facilities of direct and speedy 
communication with all portions of this country, through 
regular correspondents — several thousand in number — 
together with agents in Europe, all combine to enable us 
to prosecute patent business at rates more favorable to 
inventors and those interested in such matters than other 
responsible solicitors seem disposed or able to offer. 

We assure those who desire our advice or efforts in any 
matters relating to Patents, home or foreign, that they 
will have accurate information — prompt and constant 
attention. 

If two or more of these pamphlets should come into the 
hands of one person, it is respectfully asked that one be 
retained, and the other, or others, be given to those who 
might desire the information contained.

To whom Patents are Issued. 

According to the new Patent Law, approved July 
B, 1870, a patent will be granted to any one who has 
invented or discovered any new and useful art, ma- 
chine, manufacture, or composition of matter, or any 
new and useful improvement thereof. Whether the 
invention claimed be made by a man or woman, citi- 
zen or foreigner, a patent is granted in the name of 
the person first discovering and perfecting the de- 
vice. If the inventor die before obtaining a patent, 
his or her legal representative can procure it. 

If inventors unite in any application, the patent 

issues to them jointly. Great care should be exer- 
cised before signing a joint application, because if 
tbe applicants are not joint inventors, the patent ob- 
tained thereupon will bo of no valne. 

If the inventor, before obtaining a patent, assign 
a portion of the right, the patent will be issued upon 
request to the inventor and purchaser, as assignees, 
jointly. If the whole of the inventor's right be 
assigned, the patent will issue to the assignee, but 
the assignment must first be recorded in the United 
States Patent Office. 



G-eneral Information. 

The first question to be settled, when a person im^ 
found out any useful device, process, or compound, 
is, has it been patented f 

Any one desiring this information may send i<s a 
written description or sketch of the device, upon 

(7) 



\ 




receipt of which we will make a preliminaiy exami- 
nation at the Patent Office. If such a p^itent has 
been issued, we shall state the fact, and advise the 
person either not to incur the expense of paying the 
Government fee of $15 for an application, or, when 
it is possible, direct him to so change or modify his 
device as to make it patentable. 

Our experience in the business enables us fre- 
quently to give valuable aid in this particular. For 
making the preliminary examination and giving this 
information we charge no fee. 

This examination will generally enable us to give 
positive information to an inventor whether or not 
a patent will be allowed him, but nqt always. Ap- 
plications are sometimes made, when a caveat has 
been filed in the secret archives of the Patent Office, 
of which no one but such as are officially connected 
with the Department can have any knowledge. 
Sometimes the Examiner may make an erroneous 
decision, or base one rejection on the fact that an 
application for a device of similar character had pre- 
viously been rejected; or it may be that the inven- 
tion, or one embracing it, had been made and pub- 
licly advertised, but not patented, and therefore not 
within the ordinary scope of examination in the Pat- 
ent Office. 

But these are exceptional instances. As a gene- 
ral rule, the preliminary examination enables us to 
advise our clients whether or not a patent can be 
obtained with comparative certainty. 

If we inform our client that the device can be pat- 
ented, we shall also prepare the necessary papers 



complete for the signature of the inventor, bo that 
he will only have to sign them in the proper form 
and manner, which the instructions we send with 
the application will plainly indicate. 

Models and drawings can be furnished at our oflBcc 
for the actual cost, or may be sent us by the invent 
or. They should be provided in time to be submitted 
ivith the application. At the same time $15, which 
the law requires shall be paid to the Government on 
filing the application, should be furnished us, either 
by post-office order, registered letter, or draft on New 
York. The cost of the drawing should be sent at 
the same time. In ordinary cases this will be $5. 
When the patent is allowed, the law requires another 
sum of $20 to be paid to the Government before the 
Letters Patent are issued, making the amount the 
Government receives for each original patent allow- 
ed S35. 

Our fee of $25 is duo and payable when the patent 
is allowed. By this arrangement we receive no fee 
unless successful in our efforts to obtain the patent. 
When solicitors obtain the fee in advance, and the 
patent is not allowed, the inventor loses whatever 
fee he has paid the solicitor, besides the Government 
charge. For the benefit, however, of those who pre- 
fer to pay in advance, we state that we have no ob- 
jection to receiving our fee in this manner. 

It is very often thought by inventors that by a 
personal visit to Washington, and attendance at the 
Patent Office, they can obtain their patents "without 
the aid of attorneys^ and with, less delay and uncer- 
tainty. It rarely happens that an inventor, unless 



10 



APPLICATION. 



he is also a patent lawyer, can secure his best inter- 
ests without the aid of an experienced attorney, and 
it is seldom that his patent can be better obtained 
by his personal presence than by correspondence 
with reliable attorneys resident here. The expense 
of the journey in most instances would be more than 
the ordinary cost of obtaining a patent through our 
offices. 



Application. 

The application comprises a model, drawings, pe- 
tition, oath, specification, aud the first Government 
fee ^f $15. 

^11 applications must be completed for examina- 
tion within two years after the filing of the petition ; 
and, in default, they will be regarded as abandoned, 
unless it be satisfactorily proved to the Patent Office 
that such delay was unavoidable. 

Upon presenting an application to the Patent Of- 
fice, it is referred to a primary Examiner, who ex- 
amines it with reference to its novelty and usefulness. 
If he find or believe the invention unlike all other 
devices known or described, either in this countrj^- or 
elsewhere, or an improvement upon some one, and 
that it is susceptible of use and not hurtful, a patent 
is allowed. 

If, on the contrary, any model, drawing, specifica- 
tion, or published description of the same thing be 
found in this country or elsewhere, the application 
is rejected. 




If the Examiner should, for any reason, object to 
the allowance of ail that is claimed, we endeavor to 
overcome his objections by obtaining a re-hearing and 
explaining away tlic points he raises, or modifying 
the specification so as to avoid his objections. T^. 
however, he reject the application, and we think his 
decision unreasonable or unwarranted, we advise our 
client to appeal to the Examiners in Chief, and if 
their decision is against the interest and what we be- 
lieve to be the legal right of our client, we advise an 
appeal to the Commissioner, and from him, if neces- 
sary, to the Supreme Court of the District of Columbia. 
For obtaining and conducting a re-hearing we make 
QO charge. Some solicitors charge additional fees of 
from $25 to $100, or more. Indeed, it is alleged that 
unscrupulous attorneys purposely file informal, de- 
fective, or objectionable applications, so as to necessi- 
tate a re-hearing and enable them to make additional 
charges, and thus they not only obtain more money 
than they call for by their advertised terms, but dam- 
age their clients by subjecting them to unnecessary 
delay. 

Thus, suppose the device is for an improvement vi^on 
a machine already patented. The attorney can claim 
it both as an original invention and an improvement. 
The patent will be rejected. The attorney notifies 
the inventor of the rejection, but suggests that for a 
further fee of S25 or $50, he can obtain a re-hearing 
and an allowance of the patent. The credulous in- 
ventor forwards the extra fee, and the attorney ob 
tains a patent by simply erasing the objectionable 
claim from the specification. 



12 APPLICATION. 



But these re-hearings are of frequent occurrence 
also where the best faith is observed towards clients ; 
for if the attorney performs his whole duty, he will 
make the claim as broad as possible, including not 
only what the inv'entor is certainly entitled to, but 
all that is open to argument. 

If the Examiner, after argument, hold that the 
claim is too broad, the objectionable portion, by the 
re-hearing, can be abandoned, and the specification 
so amended as to obtain for the inventor all that is 
patentable. 

For these re-hearings the Government requires no 
fee. 

As we ask no fees in advance, and no fees for mak- 
ing preliminary examinations and obtaining re-hear- 
ings, those who intrust their business to our hands 
run no risk of paying exorbitant or unnecessary 
charges, but are assured that their interest in obtain- 
ing a patent at the least possible expense, and our 
interest in obtaining the same with the least possible 
delay, are both considered and subserved. 

It usually takes about four weeks to obtain allow- 
ance of Letters Patent. Sometimes, when the Office 
IS pressed with business, the applications being ex- 
amined in turn according to date of filing, a longer 
time is required. Again, it often happens that we 
obtain the allowance of a patent in two weeks, and 
sometimes within a few days. 

We also avoid delay in the following manner: We 
make it an invariable rule to file the application in 
the Patent Office as soon as practicable after 
receipt ; and should there be need of greater haste 



MODELS. 13 



from any cause, our large and thoroughly-organized 
establishment will enable us to file the case, if re- 
ceived in the morning's mail, on the day of its receipt, 
provided the drawings required be not too elaborate. 



Models. 

The rules of the Patent Office prescribe that ap- 
plications for patents should be accompanied by a 
working model in cases where the nature of the 
invention admits of one. As a general rule this 
model must not exceed twelve inches in length, 
width, or height. It must clearly show every feature 
of the machine or device, which forms the subject 
of a claim for invention; but should not include 
other matter, unless necessary to the exhibition of a 
working model. 

Where an important invention has been made, 
and the inventor has not time to prepare a finished 
model, he can send us a rough one, with which we 
will prepare and file his case. The finished model 
can be sent afterward, if required. A model is 
always demanded under the new law by the present 
Commissioner of Patents, and therefore we advise 
its preparation in every case where it is possible. It 
is better not to use glue in making the model. 

Models must be neatly and artistically constructed. 
They must also be made with reference to durability, 
and, if possible, should be in working order. Let 
them be painted or varnished, if made of wood. The 
inventor's name should be put on the model or sent 
with it, so that we can tell to whom it belongs. 




Inventors are especially requested, in sendit/^* mod- 
els, to send^ in the same box with the model, a slip 
of paper giving the name and address of the inventor. 
When models come to us without the invtjnto/s name 
attached, either by card, marked in pencil, or somo 
such way by which they can be identified at once, 
they are liable to be delayed. 

Patent medicines, compositions of milter, chem- 
ical compounds, and the like, do not adn?f fc of models; 
but it is required that samples should accompany 
the application for such patents. 

In transmitting either models or samples, we 
should be informed in writing of the uses and mode 
of operating the machine, and of compounds the pro- 
portions of the ingredients used, as well as the 
method of compounding them. Such description 
aids us materially in preparing the specification. 

By provisions of the new postal law, now in vogue, 
models and merchandise of various descriptions, in 
packages not exceeding four pounds in weight, can 
be sent by mail at the rate of eight cents per pound, 
or half a cent an ounce. This is a wonderful con- 
venience for the public, especially for residents in 
distant places inaccessible by rail. But in sending 
models by mail, our correspondents should remem- 
ber that the box or package must have openings in 
it, so that the contents may be observed by the post- 
master; otherwise, or if the package is sealed, letter 
postage, or six cents an ounce, is chargeable on de- 
livery. A little care Avill therefore save the sender 
considerable money. 

Generally, however, models should be carefully 




boxed ai)d forwarded to us by express, charges pre- 
paid; and in all cases the inventor's name should be 
marked in pencil, or otherwise, on the model or in- 
side of the box. If liable to be broken, the model, 
whether sent by mail op express, should be packed 
in a strong box, and should be so secured to the box 
that it cannot move therein. 

Although the model does not form a part of the 
specificatirn, it is an important feature in the appli- 
cation, and worthy of more attention than is usually 
bestowed upon it, for the following reasons: 

1. It is a strict rule of the Patent OflSce that no 
claim can be made upon any device, or part thereof, 
not shown in the model exactly as claimed. 

2. The model is often the only means whereby the 
solicitor can exemplify to the official the advantages 
of the invention in a practical light, workshops and 
factories being scarce in this locality. 

3. The model is the inventor's safeguard. If his 
papers have been prepared in a bungling manner, 
with untrue drawings, bad descriptive matter, and 
weak or false claims, he has by the terms of the law 
recourse to his model, and may file a new application, 
with new drawings, descriptive matter, and claims: 
in accordance with which, if true to his model, the 
patent will be reissued to him. When it is consid- 
ered that most valuable inventions are protected by 
reissued patents, the importance of a strong and 
carefully- made model will not fail of due appreci- 
ation.

SPECIAL ADVICE REGARDING MODELS. 



Special Advice Regarding the Constniction 

of Models. 

In making models for mere preliminary examina- 
tion, the following methods may be resorted to for 
cheap and rapid work: 

Lead or pewter rivets are convenient, easily form- 
ed, and will answer sufficiently well for temporary 
work. Small gear can be readily made of stiff leather. 
This is easily cut with a pocket knife into gear and 
into many other parts of machines. It will not break, 
is a little flexible, and answers all purposes for most 
models. Gear can often be made also by corrugating 
a strip of tin. Bevel gear can be most easily made 
of wood or of leather mounted on a disk of wood. 
Driving belts can be made of round shoe laces, and 
serve all the purposes required for models. Eubber 
bands are entirety worthless, and go very much 
against the value of an invention in the Patent Office. 

In making handles for models of plows or culti- 
vators, bent wood is always best. If they are whit- 
tled out of straight-grained soft wood, or even black 
walnut, they are invariably broken before reaching 
us. Wire or hent wood are always best. 

In making models, if the wood- work is slight and 
the metal parts rather heavy, be particular, in ship- 
.ping them to us, to pack the metal parts securely. 
Many such come to us with the metal only slightly 
supported with packing, such as loose paper, cotton, 
&c., while the wood are very securely packed; the 
consequence is that the metal parts are dismounted 
and the whole contents of the box are in a mass of 
ruins when it reaches us. 




Do not paste, gum, or glue alphabetical letters or 
numbei-s on models of wood or metal. If the wood 
has been oiled, however dry the oil may have be- 
come, the letters will curl off and become lost before 
the box is received. This is especially so of metal 
models. If they appear to stick well at first, changes 
of temperature invariably loosen them, even if put on 
with the strongest glue. Then such references by let- 
ters in the description are worse than useless. Make 
such letters on wood with ink or pencil ; on metal, ink 
will do if all the oil is wiped off with chalk. If ink does 
not take, use paint, or scratch them on with a file. 



Drawings. 

The applicant for a patent is required by the law 
of 1870 to furnish drawings where the nature of thb 
case admits of them. The drawings must be neatly 
and artistically executed, according to certain rules 
prescribed by the Patent Office, which varj^ with 
every Commissioner, and which, therefore, we do 
not state. As the law of 1870 allows photographic 
duplicates to be folded in the Letters Patent, the 
drawings are made with especial reference to that 
art. The draughts should be executed on one or 
more sheets, separate from the specification, the 
size of the sheets to be fifteen inches from top to 
bottom and ten across, one inch being for the mar- 
gin. These drawings, which are to be kept in the 
Patent Office for reference, must be on thick, calen- 
dered drawing-paper, sufficiently stiff to support 
itself upright in the portfolios. Tracings upon cloth, 
pasted upon thick paper, will not be admitted. 




The drawings should generally be in perspective, 
with such detached sectional and plan views as will 
clearly show the invention, its construction, and op- 
eration. All drawings should be correct in outline 
Dnd shade, and, when different materials are united 
in a machine, as steel and iron, or wood and metal, 
the distinction should be indicated. Each part must 
be distinguished by the same number or letter, when- 
ever that part is delineated in the drawings. Per- 
fect clearness and perspicuity in the drawings are 
essential to a proper understanding of the specifica- 
tion by the office. It is almost impossible to have 
drawings made to suit theconstantly-changing rules 
of the Patent Office outside of this city. 



The Speciiication. 

This is a most important part of the application. 
Much knowledge and skill should be bestowed in its 
preparation. No one who has not made it a study 
and business for years is well qualified to prepare a 
specification. Thorough scientific and legal attain- 
ments are indispensable. Many inventors have dis- 
covered, by painful and costly experience, that it is 
not every specification which will bear the search- 
ing scrutiny to which it nuist necessarily be sub- 
jected in an action of infringement. 

A patent for an invention is a letter of protection, 
issued under seal ofthe Interior Department, granting 
to the patentees the exclusive right to make, use, 



THE SPECIFICATION. 19 

and sell the invention, which is the subject of the 
paper. But the right to combine or manufacture 
the gifts of Providence, according to the skill we 
have, is fundaniental, and the best interests of civil- 
ization require that this right shall not be inter- 
fered with. Therefore, a patent is necessarily lim- 
ited and prescribed in its terms, and the perfection 
of such a paper is reached when, without going into 
the common ground where all men have equal rights, 
it marks out fully and completely the field of inven- 
tion in such clear and concise terms, that there can 
be no error or misunderstanding. 

It seems a simple thing to describe an invention, 
and to draw a claim which will include the full scope 
of its principle, yet there is required an experience 
and combination of mental faculties and acquire- 
ments not often found. With a scientifically accu- 
rate perception must be joined a practical acquaint- 
ance with the arts and manufactures in their present 
state of improvement, correct knowledge of the legal 
force and meaning of terms, and high power of 
analysis. And we ought to include the draughting 
faculty. 

A scientifically accurate perception is required to 
enable the writer to see clearly the exact points of 
improvement wherein the invention, which is the 
subject of his paper, differs from articles in common 
use or already patented. Such points of improve- 
ment must be seized, as by intuition, and held up 
clearly in their full bearing. 

Practical acquaintance with the arts and manufac- 
tures gives a proper appreciation of the advantages 



of the invention under consideration, and the power 
of describing it in such clear terms, that those skilled 
in the art to which it relates will be able to make 
and use it. If the advantages are not fully set forth, 
there will appear no invention to the Patent Office 
examiner. If the description be not in clear and 
lucid terms, the patent will be defective. 

Knowledge of the legal force and meaning of 
terms is most essential, as the patent is a legal 
document, in the nature of a grant. While, there- 
fore, a legal education is essential, it does not foHow 
that every lawyer can prepare a sound and valid 
specification; for he may be totally unacquainted 
with the terms of the art or manufacture to which 
the invention appertains. 

Power of mental analysis : here it is that most 
failures are made. The description in the body of 
the specification may be accurate and concise ; but 
the claim, which is the gist or soul of the paper, will 
frequently relate to unessential parts of the inven- 
tion ; or it will be simply a shortening or condensa- 
tion of the descriptive matter. Instead of these, the 
claim should embrace such parts, and those only, in 
which lies the spirit or principle of the invention. 

As the drawings form an essential part of the 
specification, they should be clearly and accurately 
made. ' The drawings of patents are often made by 
persons who understand nothing else of a prepara- 
tion of a specification, while the person who writes 
the description and claim understands equally little 
of the draught prepared to go with his te«ct, tho 
model and inventor's explanation serving as his 



guide. In this maDner a good specification will fre- 
quently avail nothing to save the character of a 
patent, because of miserable and faulty drawings, of 
which the person who wrote the specification wa? 
not competent to judge. 



Patents for Designs. 

Kovelties in the form or shape of articles or im 
pressions produced on the surface of materials bj 
any means whatever are patentable. 

Under the new law of July 8, 1870, design patents 
may be taken out for the new form or shape oi 
any article. This includes tools, patterns, castings, 
machine-frames, stove-plates, escutcheons, borders, 
fringes, and ornamented articles of all descriptions; 
also all new designs for printing, weaving, painting, 
or stamping upon cotton, silk, or woolen fabrics, cal- 
icoes, carpets, oil-cloths, prints, paper-hangings, etc.; 
also labels, envelopes, boxes, and bottles for goods; 
likewise all works of art, including prints, paintings, 
busts, statuary, compositions in alto relievo and has 
relief, new dies, impressions, or ornaments to be used 
on any article of manufacture or architectural work. 

The Government fees upon this class of patents 
are stated on page 37.

22 TRADE-MARJIS. 



No models are necessary in these cases, but draw- 
ings or photographs are required, which should not 
exceed eleven inches by seven-and-a-half in size. If 
photographs are furnished, ten extra copies must 
also be sent. The negative is no longer required. 

For obtaining a design patent our fee is only $10. 



Trade-Marks. 

New provisions are made under the law of July 8, 
1870, for the protection of lawful trade-marks by 
Letters Patent. In order to obtain such Letters 
Patent, we require — 

1. The name of the party or firm, (and if a firm, 
the names of the parties,) their residences, and place 
of business. 

2. The class of merchandise, and the particular 
description of goods comprised in such class, by 
which the trade-mark has been or is intended to be 
appropriated. 

3. A description of the trade-mark itself, with ten 
fac similes thereof, and the mode in which it has 
been or is intended to be applied. 

4. The length of time, if any, during which the 
trade-mark has been in use. 

5. The necessary funds, including the Government 
fee, $25, our own fee, $15. 

A trade-mark thus patented will remain in force 
for thirty years, and may be renewed at the end of 
that time for thirty years more, except u cases 
where such trade-mark is claimed for, and v*pp.H'^d

to, articles not manafactured in this country, and 
where it receives protection under the laws of any 
foreign country for a shorter period, in which case 
it shall cease to have force in this country at the 
same time that it becomes of no effect elsewhere. 

The right to use any trade-mark is assignable by 
any instrument of writing, and such assignment 
must be recorded in the Patent Office within sixty 
days after its execution. The fees will be the same 
as are prescribed for the recording of assignments 
of patents, usually $2, unless we prepare the papers, 
when our charge will be S3. 

Having a competent designer in our establish- 
ment, we will furnish original drawings or designs 
for trade-mark use, when it is requested. 



Oaveats. 

A caveat consists of a specification, drawling, oath, 
and petition; and, like an application, should be pre- 
pared by one of experience and skill in the profes- 
sion. 

It sometimes happens that an inventor has con- 
ceived a general idea of some device, the details of 
which are elaborate and complicated, and which ho 
is desirous of perfecting or simplifying before pre- 
senting it to the public, but to accomplish which 
requires time and repeated experiments. 

The patent laws provide for the infurmation of such 
inventors by allowing them to file a general descrip- 
tion of their devices, the objects and purposes of the 



\^^ 



"same, in the secret archives of the Patent Office. 
This general description is called a caveat, and is 
considered a confidential communication from the 
inventor to the Commissioner of Patents. 
The objects to be attained by a caveat are — 

1. The inventor is entitled to a notice from the 
Commissioner of Patents in case any person shall 
apply for a patent upon the same or similar device 
during the twelve months that ensue after the caveat 
is filed; and 

2. In case of interfering applications, the ^^caveator^* 
has secured the advantage of a prima facie case upon 
the records of the Department. 

Only American citizens, or persons who have 
made oath of their intention to become such citi- 
zens, and have resided in the United States one 
year, are entitled to file a caveat. 

We prepare drawings when necessary for caveat 
purposes at the actual cost incurred in their prepa- 
ration, making and filing the written description to 
accompany the same for $10. 

We do not in general advise the filing of caveats. 
It is far better, if possible, for the inventor to per- 
fect his invention and apply for a patent at once, 
for even at the rate we charge a caveat will cost 
from S20 to $25, including the Government fee. 

Caveats can be renewed every twelve months by 
paying the Government fee of $10 for each renewal. 
If not renewed, the present practice of the Patent 
Office is to throw them open to the inspection of the 
public.

Interferences. 

] t often occurs that applications are pending from 
different persons for the same device at the same 
time. In such cases the respective parties are noti- 
fied of the fact, and their applications are placed in 
a position technically called ^'iDterference." Each 
party is then expected to make out the best case 
possible consistent with truth and justice, and the 
question as to which shall have the patent is deter- 
mined by the Commissioner, after hearing the proofs 
and allegations submitted hy the contestants. 

Sometimes the devices of several inventors are in 
interference, and a decision as to the respective in- 
terests of all concerned can only be procured after 
much labor has been performed by the attorneys. 
It is impossible, therefore, to nx a definite fee. Our 
charges will be reasonable and satisfactorj'. 

In these litigations the steps are — 

1. The filing of the preliminary statement or 
simple affidavit, setting forth the date of making 
the invention, and the movements of the inventor 
towards perfecting the same and reducing it to prac- 
tice. 

2. Taking the depositions of the inventor and his 
corroborating witnesses, and cross-examining the 
witnesses of his opponent. 

3. Argument before the Patent Office tribu- 
nals. 

As there is by law no appeal, in a case of interfer- 
ence, from the decision of the Commissioner, it is 




apparent that these steps should each be carefallj 
taken under the guidance of counsel conversant 
with patent litigations. Having had many years 
experience in such conflicts, we are prepared to act 
for the best interests of our clients. 



Re-Issues. 

The Patent Law authorizes the re-issoe of Letters 
Patent, and provides thereby a means of remedying 
its defects. 

Such re-issued Letters Patent correspond in date 
with the original, and are granted to the assignees, 
as well as to the inventor. In all cases, how^ever, the 
application must be made and the specification sworn 
to hy the inventor. 

It should be carefully borne in mind that — 

1. No change or improvement in the invention 
can be introduced into the re-issue application. 

2. For even the slightest new feature or improve- 
ment, a new application for original patent must be 
made. 

This provision of the law has given rise to a very 
important department of our business. It has been 
found by those conversant with actions of infringe- 
ment that the Letters Patent may be defective in one 
or more of the following particulars: 

1. The specification may not be drawn up in such 
full, clear, concise, and exact terms as will enable a 
person skilled in the art to make and use the inven- 



.j\ 



EXTENSION OF PATENTS. 27 

tion. The Patent Office does not guarantee that the 
Letters Patent are correct in this respect. The draw- 
ings connected therewith naay not clearly illustrate 
the invention. 

2. The claim may be too broad, covering more than 
the actual invention, or. in other words, embracing 
what is not new. This defect may be remedied by 
disclaimer or re-issue. The latter remedy will im- 
prove the papers, besides obviating the defect. 

3. The claim may be too narrow, not embracing 
the entire invention. This is a most frequent error, 
and it can be corrected only by re-issue. It is not 
always the fault of an attorney (although too often 
so) that the claims of an original patent are limited. 
The practice of the Patent Office is well understood 
to be more favorable to the granting of full claims 
under a re-issue than on the original application. 

We examine the character, validity, and scope of 
Letters Patent, with a view of determining upon the 
advantage of a re-issue. 

If, in view" of this examination, a re-issue is deemed 
advisable, we will undertake to obtain it at a reason- 
able cost, varying from $25 to §50, which sum shall 
be payable only in case we are successful. 

The Government fee is $30; draughtman's fee usu- 
ally $5, and Abstract of title $5. 



Extension of Patents. 

Prior to March 2, 1861, the lifetime of a patent was 
fourteen years; but provisions were made by law for 



their extension for a further term of seven years 
This class of patents has now expired, except 
when extension has been granted. Extensions are 
sometimes granted by direct Act of Congress, when 
the circumstances are favorable. We appear for 
clients in such cases before the CongreBwonal Patent 
Committee. 

All patents (except for designs and trade-marks) 
granted since March 4, 1861, have a lifetime of seven- 
teen years, and cannot be extended except by act 
of Congress. 

Design patents are granted for three-and-a-half, 
se*ven, or fourteen years, at the will of the inventor, 
by application therefor, and the payment of fees men- 
tioned on page 37. 



Infringements. 

Every patentee or manufacturer commencing busi- 
ness desires to know, before he is put to great 
expense, whether he is liable to be stopped in work- 
ing his patent or manufacture. 

The question as to whether one patent infringes 
another lies at the basis of nearl}^ all patent litiga- 
tion, and its phases are as varied as the patents 
themselves. Each case rests upon its own peculiari- 
ties, and a safe and reliable opinion therein is gener- 
ally the work of days or weeks, and involves great 
research. 

Every year adds to the labor of these invc^tiga- 



tions, on account of the increase in the number of 
patents. 

It is a part of our business to serve clients in 
this branch of Patent Law by necessary exam- 
inations at the Patent Office, and instituting or 
conducting all legal proceedings connected there- 
with in the United States Courts. For an in- 
fringement search, and legal opinion founded there- 
on, we charge according to the amount of labor, 
usually $25. 



Rejected Oases. 

We have been very successful in prosecuting 
Ciises which were filed through other attorneys 
and rejected or abandoned, and are prepared to give 
our services in such matters on terms which will 
be made satisfactory. 

Under a recent decision of the Commissioner 
of Patents it was held that rejected applications, 
formerly considered as abandoned, may be re- 
newed. Inventors having such cases can there- 
fore, if they so desire, still further prosecute them 
by making new applications. 

Upon receipt of a notification from an inventor 
that he desires so to do, together with a power 
of attorney, (see page 59,) we will prepare and 
send him the necessary papers for signature and 
execution. 



As our fees io these cases are conditional entirely 
upon our success in obtaining the allowance, it ib 
clear that it involves the inventor in no expense what- 
ever^ should we fail in convincing the Office of the 
justice of his claim. 

When an inventor addresses us on the subject oi 
his rejected case, delay will be saved by enclosing a 
power of attorney, signed and witnessed as per form 
on page 59. 



Forfeited Cases. 

Under a recent law some applicants for patents? 
whose right to the same has been forfeited by failure 
to pay the final Government fee, are allowed to re- 
vive the case, and obtain a patent, upon making 
new application and paying $16 Government fee. 



Pnblic Use and Sale of Invention. 

It IS very generally understood that, in order to 
avoid the operation of laws relating to public use of 
a device before application for a patent is made, in- 
ventors must regulate their movements with pro- 
found care and secrecj^ This is an error. The law, 
as now defined, aathorizes the public use and sale of 
inventions for two years prior to the application. 
If, however, during the time of such public use, any 
party besides the inventor shall have made and used 
the same device, the law will protect him in the use 



ROYALTY. 31 



of such as he has made, but not in any further 
manufacture of th^e article, after the date of the 
inventor's patent. 



TT^ho will Sell Patent Rights. 

Our business as solicitors, in conjunction with 
our other legal activities, forbids us from becoming 
agents for the sale of patents. Nor can we under- 
take to recommend parties to act as salesmen for 
correspondents. In four cases out of five the in- 
ventor himself is the proper person to dispose of his 
invention. He is the best judge of its merits and 
its vaiuo, and knows best whether the sum offered 
by a purchaser is renumerative or otherwise. 

We furnish, however, all the necessary papers for 
conductiog the sale or working of a patent in any 
manner. See page 38- 



Koyalty. 

This term signifies a tax or tariff, agreed upon 
between the owner of a patent and a manufacturer 
or user of the thing patented. The owner gives a 
license to the manufacturer, receiving therefor a 
stipulated price upon each article sold or used. 

Some owners of patents have been known to re- 
ceive a large income from such royalty, reaching, in 
one instance, (Blias Howe's sewing-machine,) nearly 
half a million dollars per year. 



32 



PATENTS ON SMALL INVENTIONS. 



The plan of license and royalty is frequently pref- 
erable to sales of patents. We prepare all necessary 
papers in such cases for a fee of $5. 



Marking Articles, Patented or other- 
wise. 

By the act of Congress, approved July 8, 1870, it 
is provided, that all articles made or vended under 
the protection of a patent must be marked, by affix- 
ing thereto the word "patented," together with the 
day and year that the patent was granted. 

In eases where it is impracticable to mark every 
article, the law provides that they may be sold in 
packages, and that the word "patented,'^ with the 
date of patent, shall be printed on the outside of the 
packages. 

No damages can be collected for an infringement 
of a patent where the inventor fails to comply with 
these rules. 

Stamping or marking the words "patented/' "let- 
ters patent," or the like, upon any article not pat- 
ented, subjects the offender to a fine of $100 for each 
offense. 



Patents on Small Inventions. 

Nothing illustrates more clearly ihe wisdom of 
the proverb, " despise not the day of small things," 
than small inventions. The records of the Patent 
Office present hundreds of instances where almost 



PATENTS ON SMALL INVENTIONS. 33 



princely fortunes have been realised from what at 
first seemed a .trifling invention. The "Jumping- 
Jack" has made a dozen small fortunes; and yet it 
is but a toy, and possesses no mechanical utility. 

An improvement on a simple straw-cutter yielded 
the inventor over $40,000. A patent for printer's 
ink brought the inventor much more than this. 
Large fortunes have feeen made out of the gimblet- 
shaped screw. A client of ours is to-day rich from 
the sale of an improved ^'stop-cock," which is not 
above the comprehension of a child. We could name 
minor inventions by hundreds not less successful. 

The test of all patents is their adaptability to 
general use; and, if they reach into our daily needs, 
it is easy to see how a small profit on a single article 
would yield a fortune. Indeed, the experience of 
dealers in patents, as well as inventors, teaches the 
general advantages of minor patents over those in- 
volving large outlay in their use and large capital 
to introduce them in the market. Many inventors 
of complicated and invaluable machineiy have died 
in poverty, while their heirs or some fortunate 
assignee tell off their wealth, derived from the in- 
ventor's genius, by hundreds of thousands of dollars. 
A moment's reflection will explain why this is so 
often true. It should not discourage inventive genius 
from the higher walks of inspiration, but should en- 
courage those who have conceived some seemingly 
simple device. 

Money is the motive-power of the world. The 
artist, the statesman, the soldier, the professional 
naan, understands this. Why should not the inventor? 
3 




The poet or artist who disdains to profit by his 
inspiration will surely abbreviate not only his power 
to be useful, but his individual happiness. The in- 
ventor who easts aside a simple contrivance, and 
refuses to profit by it, because he is reaching out for 
fanve and glory from some great conception, will go 
down to posterity a visionary, and some practical 
man will reap the rewards of his labor. We say, 
then, do not smother a thought because it seems to 
stop with the discovery of a small thing. 



Foreigners, 

Our Government grants patents to foreigners 
upon the same terms as to our own citizens. The 
late discrimination against Canadians no longer ex- 
ists. They can make application on the same terms 
with citizens of the United States. 



Patents in Foreign Countries, 

Many inventors and others have made fortunes 
by obtaining Letters Patent in Great Britain and 
other European countries. As a general rule, per- 
haps it is not safe to say that etrcry device worthy 
of an American patent should also be patented 
abroad; but there can be no doubt that too little 
attention has been given to this subject. 

The results of the Vienna Exposition exhibited 
clearly, and the U. S. Centennial Exhibition has 



:~i 



PATENTS IN FOREIGN COUNTRIES. 35 



largely increased, the high estimation in which 
American machinery and inventions are held in Eu- 
rope. The chief mechanical premiums were awarded 
to American exhibitors, and nearly all the articles 
sent to the Exposition were sold to foreigners. 

The Government fees for obtaining patents in all 
foreign countries must be paid in gold or its equiva- 
lent. As the price of gold is constantly fluctuating, 
any tariff of prices would necessarily be unreliable. 
Should inventors desire foreign patents, we will give 
all required information as to the cost in each case. 
An approximate schedule is appended. 

IN GEEAT BEITAIN 

Patents are granted for fourteen years to any person 
who applies, whether he be the inventor or an im- 
porter of the invention. A British patent extends 
over Great Britain and Ireland only. For the Colo- 
nies a separate application must be made. 

IN FEANGE 

Patents have a lifetime of fifteen years. Annual 

fees, $20. 

IN BELGIUM 

Patents are granted for twenty years, the patentee 
paying a small annual fee. 

When foreign patents are desirable, the three 
countries above named generally afford a better 
field of operations than all others. 

The taking out of a patent in a foreign country 
does not prejudice a patent previously obtained 
here, nor does it prevent obtaining a patent here 
subsequently 



3G 



PATENTS IN FOREIGN COUNTRIES. 



When application is made for a patent for an in- 
vention which has been already patented abroad, 
the inventor will be required to make oath that, 
according to the best of his knowledge and belief, 
the same has not been introduced into public and 
common use in the United States. 

An applicant who has obtained a foreign patent 
should (temporarily) file in the Patent Office in this 
country the patent so obtained, with the specifica- 
tions (provisional or complete) attached, or a sworn 
copy of them. But where such papers or copies 
cannot be conveniently furnished, it will be sufficient 
if the reasons of such inability be set forth by affi- 
davit; and the applicant shall also state the fact 
that a foreign patent has actually been obtained, 
giving its date, and showing clearly that the inven- 
tion so patented covers the whole ground of his 
present application.

notice thereof sent to the applicant or his agent; 
and if the final fee for such patent be not paid within 
that time, the patent will be withheld, and the in-

application, take the steps required to prevent for- 
feiture.

Onr Fees. 

For preliminary examinations, no fee. 

For preparing application, specification, and 
all necessary papers, and attending to the 
business until a patent is allowed, in ail 
ordinary cases (drawings excepted) $25 00 

For preparing drawings, the cost thereof, 

usually 5 00 

For preparing and filing caveat 10 00 

Under recent rules all patents are printed; there- 
fore copies of late specifications can be obtained at a 
less rate than formerly, provided application is made 
before the printed copies are exhausted. 

We will obtain a copy of the claims in any case 
where the patent has issued since 1836 for $1. The 
copy of the specification is charged for in proportion 
to its length, and a copy of the drawings will be 
furnished for the draughtman's fees only. 

We furnish all information that may be desired 
as to patents which have been granted or rejected, 
as to assignments, contracts, licenses, shop-rights, 
joint ownership, letters, abstracts of deeds of trans- 
fer, name of patentee, also sketches from drawi^igs 
and deseriptions from the specifications of any par- 
ticular patent. For giving such information our 
charge is only sufficient to pay for the time and 
labor. 

Assignments, transfers, licenses, or contracts, re- 
lating to inventions, should in all cases be recorded 
in the Patent Office. For preparing the necessary 



papers in such cases, and having the same recorded^ 
our fee is $3; for recording only, $2, 

All cases of interference as to patents, here or else, 
where, and any litigation, will be conducted for such 
reasonable compensation as may be agreed upon. 

All letters of inquiry, containing a postage stamp, 
will be prom_ptly answered. All communications 
about patents will be treated as strictly confidential 



Engravings, 

We call the attention of inventors to the relief 
plates, prints of which are shown on pages 53, 54. 
These plates are produced by an application of the 
heliotype process from the official copies made in 
the United States Patent Office. Any inventor or 
patentee may thus obtain, at a trifling cost, a perfect 
fac-siniile engraving from the official drawing of his 

invention. 

» 

The plate itself is blocked, ready for use, and ca- 
pable of being worked on any prititing-press, with 
or without type. We are enabled to furnish these 
plates at Six Dollars each.

CANADIAN PATENTS. 41 



Copy-Rigiits 

The Patent Law of July 8, 1870, provides tbut any 
citizen or resident of the United States who is the 
author, inventor, or proprietor of any book, map, 
chart, dramatic or musical composition, engraving, 
cut, print, photograph, painting, drawing, chromo, 
statue, statuary, etc., may secure a copy-right of 
twenty-eight years' duration. 

The mode of procedure is to record the printed 
title of the book, or printed description of the photo- 
graph, etc., in the office of the Librarian of Congress. 
This must be done before the book or composition is 
published. Two copies or specimens of the book or 
composition to be copyrighted must also be forwarded 
to the Librarian of Congress within ten days after 
publication. If a work of art, a photograph thereof 
should be transmitted in the same manner. 

We p:ive especial attention to this class of cases, 
and will furnish all needed information and instruc- 
tion upon request and for a fee of $5. 



Canadian Patents. 

Under the new Canadian Patent Law, citizens of 
the United States can secure patents in that country 
on the same terms as resident Canadians. The popu- 
lation of the dominion is 6,000,000, and it comprises 
the provinces of Nova Scotia, New Brunswick, On- 
tario, Manitoba, and British Columbia. The close 
proximity of its territory to our own makes it a

valuable country for American inventors, and one 
well worthy their attention. 

If the invention has already been patented in this 
country, application must be made within one year 
from the date of the American patent. 

Canadian patents will be granted for the terms 
below mentioned, and the fees, including Govern- 
ment and our own, with expenses of preparing the 
specification, original and duplicate drawings, agen- 
cy, and all charges, are as stated opposite the respect- 
ive terms, payable in United States currency. 

For a patent for five years ^^ $40 00 

For a patent for ten years 60 00 

For a patent for fifteen years 80 00 

The applicant may, at the outset, have the patent 
issued for either of the above terms of years. 

The holder of a five-year patent is entitled to the 
privilege of two extensions, each for a period of five 
years, making fifteen years in all. The holder ol a 
ten-year patent is entitled to one extension of five 
years. The expenses attending an extension are 
about fifty dollars, including the Government fee. 

Persons desiring to apply for Patents in Canada 
are requested to forward us by express, charges pre- 
paid, a model of their invention, with a description, in 
their own language, showing its merits and opera- 
tion, remitting at the same time the necessary fees 
for such a term as they may desire. We will then 
immediately prepare the drawings and specification, 
and send them to the applicant for his signature 
and affidavit. The name of the applicant in full 




(middle name iocluded) should be stated, as well as 
his occupation. 

In all eases susceptible of illustration by a model, 
one must be furnished, made to any convenient 
scale, the dimensions of which should not exceed 
twelve inches. 

Canadian patents may be assigned in whole or in 
part, and the assignment must be registered at 
Ottawa. The assignment first put on record is valid 
against all subsequent ones. Our charge for pre- 
paring an assignment and attending to its record 
is $8. 

During the first year of the Canadian patent, the 
patentee may have his improvements manufactured 
in the United States, and sell the same in Canada; 
but within two years from the date of the patent 
the manufacture must be commenced in Canada; 
otherwise the patent becomes void. The formality 
of manufacture can be easily arranged. 



Registration of Labels. 

By an act of Congress approved June 18, 1873, it 
is provided that prints and labels may be registered 
in the Patent Office. By the word *' print" is meant 
any device, word, or figures, (not a trade-mark,) im- 
pressed directly upon the articles of manufacture, to 
denote the name of the manufacturer, place of manu- 
facture, &c. By the word "label" is meant a slip 
of paper, or other material, to be attached to manu- 
factured articles, or to packages containing them. 



44 AGENTS AND ATTORNEYS. 



and bearing the name of the manufacturer, direc- 
tions for use, So. A certificate of registration will 
continue in force for twenty-eight years. The Gov- 
ernment fee is $6 ; our fee, $4. Send the label or 
print, with funds, to the address of this House. 



Agents and Attorneys. 

Agents and attorneys are requested always to 
send the inventor's name in their letters to us, 
although we never correspond with the inventor 
when an agent or correspondent has charge of a 
case. Also, when writing to us in relation to two 
or more separate and distinct inventions, do not 
write about them on opposite sides of the same 
piece of paper, as, when different descriptions are so 
written, we cannot put them in separate file-wrap- 
pers. Eemember that our entire records are classi- 
fied, or alphabetically arranged, in the inventors' 
names. 

By observing these requests, our friends will save 
us much labor of search, and secure for themselves 
in every case a prompt answer. 



Wasliiagtofb, D. C, Jcimiary i, 1879. 
TO IjYVEjYTORS: 

About fifteen years ago we adopted the 
plan of worhing for conditional f^urs. This 
was done in the full belief that It icould not 
redound to our own disadvantage, and that 
we ivould be able^ on behalf of inuentors, to 
lessen their eoopenses and save them from 
imposition. 

The experiment has proved etrjinently sat- 
isfactory , both to our clients and to ourselves, 
and we therefore propose to continue our busi- 
ness permanently on the same plan. 

We are confident that we have rendered 
inventors important aid in introducing the 
system above referred to, and now ash them 
in return to give us aliberal share of patron- 
uge. We desire to win success by deserving it. 
Very respectfully ,
